Pigs may not fly, but they certainly do soar to the spotlight on National Pig Day.

The holiday, celebrated annually on March 1, was founded by a pair of pig-adoring sisters in 1972, the purpose being “to accord the pig its rightful, though generally unrecognized, place as one of man’s most intellectual and domesticated animals.”

Go hog wild for National Pig Day with these five facts:

Sweating like a pig? Probably not. Pigs don’t have sweat glands. They keep cool by rolling in the mud.

Pigs are incredibly smart and may even have more mental capacity than 3-year-old humans.

Baby pigs can recognize their mother’s voice, and sometimes the mama sings the piglets a lullaby while they’re nursing.

Think you can outrun a pig? The mammal is surprisingly fast and can clock a 7-minute mile.

While their eyesight isn’t great, pigs have a super sense of smell. (That’s why truffle hunters employ them to sniff out rare mushrooms.)
